As far as I know there is no such ferry connection. There are daily "ferry" connections from the island of Samos to Kusadasi, Turkey but these are only small boats just for passengers, not vehicles. I visited Samos a few years ago and that was the case and still seems to be today.
The only ways to take a car from Greece to Turkey or vice versa are a) by land (Northern Greece) or b) from Rhodes, Greece to Marmaris, Turkey.
